FS#13282 - iPod Radio Remote functionality has regressed since 3.15 stable.

Radio Remote support is incredibly unstable on the newest daily builds (presumably since 77f8c9c).

While the stable build did not actually support the FM Radio functionality (and I haven’t gotten it to work on the newest dev builds either, despite the menu option now appearing), its remote functionality worked far better. On the current builds remote buttons only work one out of several attempts to connect the device. Getting it working requires a trial and error of several reboots and unplugging/plugging the remote in repeatedly. I have also seen the buttons on the remote cause rockbox to crash. None of this behavior exists in the 3.15 stable build.

Another thing is that the buttons on the remote seem to now control rockbox’s volume when they did not used to. They should not be doing so, since the radio remote uses the iPod’s line out signal and controls its own volume independently of the player. Not to mention that these controls currently bypass any maximum volume limits set in rockbox.

Is that commit not the same one I have already linked in my issue? In any case it doesn't work correctly/reliably in my testing.

yes the link you posted above links into wikipedia instead of gerrit

Fixed. Worked for me when I tested it before posting, odd.

Can you post a link that identifies the specific remote you're using?

The official Apple Radio Remote. This one.

Cool, thanks. I found one for really cheap, and it should get here by the weekend.

Ok, I have the radio remote, and it seems to generally work as I'd expect (on a mini2g and nano2g), with the glaring exception that the actual _radio_ doesn't produce any audio – however it does tune properly, and reports DAB station information. And the audio quality out of the headphones was pretty crappy.

Then I booted into the apple firmware… and okay, this remote is clearly defective. Lovely.

The commit also does say that it only adds radio support on the 5g, and other iPods will only have remote function. I suspect on iPods other than the 5g, the remote function works better as a result. Will test on my nano 1g soon.

Maybe not. First try testing on a fresh install on the nano 1g, hit play/pause once, got

Remote briefly worked on second boot, then I tested the FM Radio option.
FM Radio option displays in menu, but does not produce output.
After exiting the FM Radio menu and returning to normal music playback, the buttons failed to work, and it crashed again after a few button presses.
